To implement smart livestock operations based on information and communication technology, a field monitoring environment based on measured data must be established. Ammonia should be managed more carefully than other environmental monitoring items because it is related to the comfort and production of livestock. Moreover, it is related to odor complaints and environmental protection issues. However, existing studies that propose ammonia measurement standards for each purpose differ from one another or are unclear, and ammonia sensors in the actual field have problems such as durability and management constraints; nonetheless, there is a lack of research on these aspects. Accordingly, for effective ammonia monitoring of smart livestock operations, the necessity of ammonia monitoring for smart livestock operations is first presented, after which a plan for ammonia monitoring of smart livestock operations, supplemented with sensor specifications and maintenance standards, is proposed. This study presents a clear measurement standard based on a comprehensive literature review, as well as an effective monitoring standard reflecting field operation information. This can lead to reliable ammonia data collection and can be a starting point for smooth smart livestock operation.
